Product Description:
The MSS200B-008-B1N-NN is a synchronous servo motor stator from Bosch Rexroth Indramat in the MSS Synchronous IndraDyn H Motors series. It serves as the stationary electromagnetic section of the motor set and generates the rotating magnetic field that drives the rotor. In industrial automation, it is paired with matching rotors to provide controlled torque for positioning axes or feed axes in machine tools, packaging equipment, and material handling lines.
During continuous operation, the stator supports a nominal mechanical speed of 800 rpm, and at standstill it can exert 65 Nm of holding torque without exceeding thermal limits. Its torque constant of 4.0 Nm/A means each ampere in the three-phase winding produces four newton-meters of torque. The drive amplifier may deliver up to 42.5 A for short bursts, allowing dynamic acceleration toward the commanded profile. Phase resistance is 2.1 Ω at 20 °C, while the inductance is 16.0 mH, which shapes current rise and helps the controller smooth ripple. A standstill current of 17.0 A sustains rated torque during holding operation.
For overload events such as rapid indexing, the electromagnetic core can reach 160 Nm before magnetic saturation, and mechanical integrity is maintained up to a maximum speed of 1200 rpm. Thermal behavior follows a time constant of 120 min, giving the system a two-hour interval between temperature transients and steady-state conditions. Back electromotive force scales with speed through a voltage constant of 363 V/1000 rpm, a value the inverter must match to avoid DC-link overvoltage during regeneration. Installation requires a minimum cable bend radius of 60 mm, while the cable also has a 16 mm jacket diameter and a supplied length of 1500 mm. The stator mass is 16.0 kg, which supports stable mounting without adding excessive load to linear slides or rotary indexing tables.
